The invention is a fluid dispensing device suited to be connected, by means of a connection element (220), to a container (C) holding the fluid that can be dispensed from the inside to the outside of the container through an actuator element (400), comprising: a suction duct (240) suited to communicate with the fluid held inside the container (C), a dispenser duct (440) in communication with the outer space with respect to the volume (V) enclosed by the container (C), a suction/compression chamber (300) that can communicate with the suction duct (240) and the dispenser duct (440), a suction valve (260) suited to alternatively allow and prevent the passage of a fluid between the suction duct (240) and the suction/compression chamber (300) when, respectively, the suction valve is closed and open, a dispensing valve (460) suited to alternatively allow and prevent the passage of a fluid between the dispenser duct (440) and the suction/compression chamber (300) when, respectively, the suction valve is closed and open, a tight membrane (500) slidingly coupled with the walls of the suction/compression chamber (300) so that it can be translated in a predetermined direction; both the suction valve (260) and the dispensing valve (460) comprise the membrane (500). The invention concerns also a system for containing and dispensing fluids (F). |

1. Device for dispensing a fluid, suited to be connected, by means of a connection element (220), to a container (C) inside which said fluid is held, said fluid being suited to be dispensed from the inside to the outside of said container through an actuator element (400), said dispensing device comprising:
a suction duct (240) suited to communicate with said fluid held inside said container (C); a dispenser duct (440) in communication with the outside with respect to the volume (V) enclosed by said container (C); a suction/compression chamber (300) that can communicate with said suction duct (240) and said dispenser duct (440); a suction valve (260) suited to alternately allow and prevent the passage of a fluid between said suction duct (240) and said suction/compression chamber (300) when said suction valve is respectively closed and open; a dispensing valve (460) suited to alternately allow and prevent the passage of a fluid between said dispenser duct (440) and said suction/compression chamber (300) when said suction valve is respectively closed and open; a tight membrane (500) slidingly coupled with the walls of said suction/compression chamber (300) so that it can be translated in a predetermined direction;both said suction valve (260) and said dispensing valve (460) comprising said membrane (500). |
